I don't think indoor hardcourts are that bad for Nadal's game. He doesn't win indoors because he puts all his energy into winning Slams and the claycourt season. If there was an indoor hardcourt Slam, Nadal would have won it by now.

Unless his knees stop him, I would say it is Federer who needs to make it to the finals

The thing about indoors is that while it doesn't necessarily hinder Nadal's game, it makes his opponents more comfortable in going for their shots. To beat Nadal, you need to be fully aggressive in your approach to the match. It's easier to do that when the conditions aren't present. More players would feel comfortable playing against Nadal indoors as his defense wouldn't be as impenetrable as it would be outdoors.
